I am a survivor of World War II from Lithuania, and recently published a book on our struggles to escape the Soviets in 1944, the flight through Germany, and the years in a DP camp in the British Zone. It is a memoir of my family's life: Father, Mother, older sister and me, called God, Give Us Wings for the prayer I uttered as a small child when it looked like the only way to escape annihilation on the ground would be to fly away. It’s available on Amazon:

By November 1945, it was a camp for Estonians, Latvians, and Lithuanians only (no Ukrainians). There was a Polish camp a few miles away. The town recorder and archivist has many documents from this period. I visited in 2011 and copied many for my memoir. Here are some photos from the camp.
